| * This tests for various things as follows: |
| * Ensures that: |
| * 1. uneccessary execs do not occur |
| * 2. the environment is pristine, users environment variable wrt. |
| * LD_LIBRARY_PATH if set are not modified in any way. |
| * 3. the correct vm is chosen with -server and -client options |
| * 4. the VM on Solaris correctly interprets the LD_LIBRARY_PATH32 |
| * and LD_LIBRARY_PATH64 variables if set by the user, ie. |
| * i. on 32 bit systems: |
| * a. if LD_LIBRARY_PATH32 is set it will override LD_LIBRARY_PATH |
| * b. LD_LIBRARY_PATH64 is ignored if set |
| * ii. on 64 bit systems: |
| * a. if LD_LIBRARY_PATH64 is set it will override LD_LIBRARY_PATH |
| * b. LD_LIBRARY_PATH32 is ignored if set |
| * 5. no extra symlink exists on Solaris ie. |
| * lib/$arch/libjvm.so -> client/libjvm.so |
| * TODO: |
| * a. perhaps we need to add a test to audit all environment variables are |
| * in pristine condition after the launch, there may be a few that the |
| * launcher may add as implementation details. |
| * b. add a pldd for solaris to ensure only one libjvm.so is linked |
